. SELF-STARTER.

To all 'whom 'it may concern .i

Be 'it known that I, EUGENE- Atieus'rii GuYo'r, aA citizen of the French Republic, re

, siding'in Issy-les-Moulineaux,-Seine, France,

lio

have invented certain new and useful Improvements in Self-Starters, of which the following is aspecification. ,Y

This invention relates toa device for self vor automatic starting of explosion engines or similar apparatus, andit relates more particularly, among the devices' of the kind in-question, to those in which the starting is insured by actingon the engine shaft.

In the devices vof the kind inquestion, known 'up to the present, the ones actingon the engine shaft vare operated either bythe expansionof a spring, or by al revioualyv compressed iluid.. Such devices ave serious disadvantages. AThose in which the expansion of a spring is used, require a very powerful spring and a comparatively complicated and delicate mechanism for cookingY the said spring, and therefore vthey are not very practical. which the expansion of a previously compressed iluid is used, is too gradual and they -produce with difliculty thevsudden impulse required for insuring the starting. Moreover, the compressed fluid must be undera 30 comparatively high pressure (about BO-atmospheres)'vv-hich requires a very strong tank', and in the case when the fluid in ques- `v tion, for instance air, is Compressed by means of apump driven by the engine, the saidvpump must' be built'with great precision and requires for its Working a great portion of the power of the engine. The inventiodhas for itsmain object to enable devices of the kind in question to be 1ccnstrucfed in such-a manner that they shall bel free from the above mentioned defects, that their operation should be better, and their construction simpler than hitherto.

I It chiefly consists in using, in devices of the kind in question; foi` driving the arrangement which acts on the engine shaft, the sudden increase of volume due to the explosion of an explosive .mixture It consists, apart from this chief arrange-i ment, in certain other arrangements which -will4 be more explicitly referred to herein'- after.

It relates more particularly to certain methcdsof carrying out the said arrangements, and still more particularly, by way of new, industrial products, to systems ofA Specification of Letters Patent.

the kind in question comprising the applil Vcation of thel said constructions, and to however is merely given by way of example. e

' Figure 1 of the said drawing, shows in vertical section a device for starting, de signed according to this invention. Fig. 2

shows in. horizontal cross-section the saine system. Fig. 3 shows finally diagrammatically the same device providedvwith parts and an apparatus suitable for driving it.

. According to this linvention, or more ac-'.

curately, according t that of methods of carrying it out, to which relates more particularly the drawing, .when it is desired to build a device for automatic starting of exlosion engines, the proceeding is as folows, or in a similar manner: n d trst of all, and as already known, a to itiied pinion b is mounted by means of a ratchet gear, either, as shown on the shaft a of the engine, or unlike shown in the drawing, on an auxiliary spindle engaging with the shaft of the engine in such a manner that the r0- -tation of the. said pinionb in the normal direction of rotation of the engine, should drive the sai shaft, while its rotation in tion on it,.and a toothed rack c is usedfor driving the said pinion. And afterward, according to this invention, for insuring the movement'of the said toothed rack c in the desired direction for rotating the said pinionfin the normal direction of rotation ofA the-"e'ngine, for 'the purposeofstarting the' said engine, is used the sudden increase of volume due to the explosion of an explosive vmixture; lor which reason tav cylinder .al

with a'piston d1 is used which is mounted on a supporting frame e in such a manner relatively to the said shaft a that its axis is in a plane normal to the axis of the said shaft, that the said toothed rack c should be d1 and -finally that the single cover d? with irection, should have no aci which the said cvlindef' is provided, should be at the end o'f the said cylinder which is farther awavfrom the said shaft. One of the ends of the toothed rack c is secured, for instance by screwing` to the said piston d, and in the said cylinder, either near its cover or in the cover, is provided, on the one hand, an admission parti which is connected to asource of explosive mixture by a. pipe Y on which is mountedan obturator or clos' ing part f* by means of which it is possible to .establish or to shut oil at will communi` cation between the said, source and the. in-L ner chamber of the said cylinder, 'and a" check valve f at the inlet of the said cylinder, and on theother handan exhaust port which is connected' to an exhaust pipegon which is mounted anfobturator or closing gartg by' means of which the exhaustrcane closed or opened at will, and fnallyia` tapped hole intov which isfscrewed. a s arking plug h., Owing to this piston? d*- ingin the pbsitionneaa-est to the loover d of the cylinder, and thefclosng parts f. and g ing closed it will be only necessa ,forY startingthe engine, to open theA inlet c osing the cylinder dY a charge of explosive.'mix ture, to close again the saidl part and` to ln- 'sure the production` of a 'spark `between the poles of- .thelsparkingplug hin order that an ex losion should take place -in the said cylin er, suddenly pushing back the piston d 'and conse uently the toothed rack c in: thendesired irection for starting the engine. Afterward, in .forder to, enable the toothed rack andthe' piston to return to their initial position, as soon as the lexplosion hastaken place, so that the apparatus shouldbe ready to be utilized for a new starting operation, use is made of: means` for insuring'automaticallyY the opening of the closing part gl as soonas` the piston ,arrives at the end of the explosion stroke (in order to allowthe ex losion products to be discharged) and the c osing of the said part as soon as the saidpiston has returned to its normalposition; which meansare pref- 4erably constituted byv a connecting rod Ag Eivoted withl one of its ends-Av to the" control andle of the said closing device or ob turator, .and with its other end tol one of the vbranchesof a leverg. with two branches, which' is pivoted in such'a manner on the supporting frame e that two pinsc1 c2 se'- cured tothe toothed rackc at'suitable points, could strike 'theother branch of the said le- A ver g' and swing it so that, the vfirst-c1 when the piston arrives at the end` of 4the ex- .'plosion stroke,vthat it insures theopening of the obturator or closing part g1, and the second c2 when the piston arrives at the end of thereturn stroke," thatit should insure the closing of the'said part; meansfor automatically returning the piston to its normal position as soon as the closing a'rt'gl is 60 opened and allows thezpijoducts o explosion to escape, which means are constituted, for -i'n'stance by means vof a'spring'i acting in 4such a manner either, unlike shown,'direct on the toothed rack c or as shown on the 0,5 plnion b, thatY when the toothed'rack c is sov part ff so asto admit into the chmbl 0f yondagiven maximum,

moved by thel action of the explosion, itA should set the said .spring v'1L which subse quently, in expanding,"vv 'willreturn the toothed -rack and the piston to their initial l position; means such as for instance av heli- 7g Cal Sprin interposed between thefcdverof the c li ',er and its piston d* for deadening t e shock 'of the Vpiston against the said cover wh'en'the said piston is returned by the sprinA z' to its initial position- 175 It 'is o viousr'A that the..explosivemixtur to be admitted intovthe cylinder'aLnmst be under a certain pressure (which, need noti.- I. exceed 4=-'kg.) in order, that' the quantity of; explosivemixtureffrequired for insuringfthe 3 0 Y operation, should be'able' tro-,pass the: said'cylinder ,owingto the simple opening of the closin -part f1; to thatendis used 'a tank cV inw' ich the explosivefmixture is coxiipressezl'` and the -sai'd tank isjp'roviderl` with a v 'press'suregage enabling the pressure Y of the explosive mixture contained thereinv to be ascertainedl at 4any moment, ,and with a safety. valve k1 preventingthefmixture in p the fsaid'ltank' :from be" gcomp'ressed be 9ol For'compressing Athee losive lmixture thejsaid tankais preferab lusedia pump" driven lby the engine itse `'Ilo-:that en ,f thefsaid pump isfpreferably secured Lto' the supporting frame e, udita-crankshaft p1; is drivenlay means 'of a seti of toothediwheels, 122,753, one 1of whichfp ismounted,.loose on the shaft a ofthe engine and can be fsecuredffto it when desired'. The said' umpv ispreferabb' built in such. a manner t at when it is 'desired to as-an p explosive mixture ,carbur'eted airnthe explo-Y sive mxture *shouldf'be formedi directly in the interior of thesaid pump, and that the 1m5 air land the carburetin `medium should fbe-- 1 come mixed in the sai vpump insa perfect manner-softhat the mixture'could bepre served in the tank c Without the carburet-g ing medium settling onthe bottom of the u0 latter. To that end, in the cover 'of tl 1esaid|\.4 pump' are" arranged two ,inletval-ve's! ,-.pf one for the air, and the other for thecar furet#` v ing medium,4 each of the said valves being; A provided with a tubular cylindrical extension f ,515 acting as theirlspindle and provided on'thef whole of its circumference near the valve with a large number-of small holes forming orifices for the return of the air for) thevalvef 115,5.' W and with sprayers` forV ,the valve p (the ex# '12g tension of the latter dipping constantly into the carbureting medium coming from aA suitable tank by meanslof a pipe g) so that; the air andthe carbureting medium can pass into the inner chamber of the v pump during the suction' stroke of the piston of the latter, only through the said small holes; Yowing to which, the air andthe carbureting medium admitted throu h `a large number of jets into the pump, come mixed in athorough 130 by means of a- Zclutchlpftmg manner. The spring p used for returning the air inlet valve to its seat, is moreover made adjustable, so as to enable the carbureting to be re ulated. In the cover of the said pump is a so provided an exhaust port p7 with exhaust valve which is connected to the tank 7c by means of a pipe 1^. Finally, the control for the opening and closing of -the obturator f, and that producing a spark between the poles of the s arking plug li, is arranged so that it is su cient simply to operate a lever or pedal in order to insure first of all the opening of the closing part fi, and then the closing of the said part, and at the same time the establishment of the current supplying the plug h. F or instance, to that end used a control lever s acting, by means of a connecting rod .s1 on the handiey of the closing part f, the said lever, alien it brought back to the position in u hic-h it insures the closing of the .said part, aun when thc said position is slightly eX- cecded, dosing at t a contact insuring the cl ung ol an electric circuit (the body, con tact t. cattery u, sparking plug gl sending an electric current into the plug, a spring 7' pushing back slightly the said lever, as soon as it is no longer operated, so as to break the said circuit at t.

lt is obvious that the invention is not in any my limited to that of its methods of cari-ying ,if out u'hich has been more partieulai y indicated, but comprises on he contrary any modifications Within the scope of the claim.

What I claim as m invention, and desire to secure by Letters Xateut is In a starting device for internal combus tion engines, in combination, a starting shaft, a cylinder, a piston therein, a piston rod connected to said piston and operatively connected to said starting shaft, an inlet valve for said cylinder, a spark plug in said cylinder, a normally open electric circuit connected to said spark plug, means for opening and closing aid valve, means controlled by said first mentioned means after the valve is closed thereby for closing said normally open electric circuit, a pump operatively connected to and actuated by said starting shaft, suction valves for controlling the admission of air and gasolene into said pump, an outlet valve for said pump, a reservoir, a conduit communicating with said reservoir and with said outlet valve, and a conduit communicating with said reservoir and with the inlet valve of said cylinder.

ln testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
